Abstract: PROBLEM TO BE SOLVED: To surely separate mold fungus and to effectively utilize its purifying ability by operating a biological reacting tank of a waste water treating device incorporating a pressure floatation device in a state in that the mold fungus may be prior species. SOLUTION: In the waste water treating device, a raw water tank 1, an anaerobic filter bed 2, the pressure floatation device 3, and aerobic filter bed 4, a treated water tank 5 and a sterilizing tank 6 are arranged in order from the upstream side of a sewerage flow, and an anaerobic treatment of the raw water is executed. Then an aerobic treatment is executed after the pressure floatation treatment. In the anaerobic filter bed 2, a small amount of air diffusion is executed from an air diffuser 8 to increase a reaction efficiency by executing a stirring mixing in the anaerobic filter bed 2 and to keep a slight aerobic state. In the slight aerobic state, so called, a dissolved oxygen concn. is kept at larger than zero and about <=1mg/l.  In this way, the state suitable to a proliferation of the mold fungus is kept, and the mold fungus is allowed to become the prior species, proliferated and effectively utilized.

Title: Method and device for restoring file by logging
Inventor: WATARI NORIYUKI
IPC: G06F12/00
Filed: 1994-12-09
Abstract: PURPOSE: To improve the maintainability, reliability and efficiency of the partial fault restoration of the hard disk of a terminal for which the capacity of the hard disk is limited and measures at the time of a file fault can not be duplexed in the terminal used standing alone such as a POS terminal. CONSTITUTION: When a job means 1 is activated, a job management means 7 uses a logging means 5 and a data saving means 8. The data saving means 8 reads the data of a data file 11 to be saved from a data file group 4 and stores them in a saving device 9. Then, they are entirely stored in a logging device 6 while a job is activated by the logging means 5. When a fault is generated in the data file 11 while the job means 1 is activated, after the hard disk is restored, the data before updating saved in the saving device 9 are transferred to the data file 11 by a file restoration means 10, the job means 1 updates the data file 11 after transfer is completed and thus, the data file group 4 is restored to a state immediately before the fault is generated.

Abstract: PURPOSE:To maintain the airtightness of an optical semiconductor element and to prevent the deterioration thereof by treating a coaxial optical semiconductor module so that the front end of the cap of the optical semiconductor element is not wetted with molten solder in a holder fixing stage. CONSTITUTION:An optical fiber 1 and an optical lens 2 are fixed by a resin and the optical semiconductor element 3 is fixed by the solder 5. The holder 4 is applied with nickel-gold alloy so as to be well wetted with the solder 5. The nickel-gold alloy is similarly applied on the cap part 31 of the optical semiconductor element 3. The front end part of the cap part 31 is previously subjected to a resin coating 32 of 'Teflon(R)', etc., to prevent the wetting with the solder 5. The solder 5 is heated and melted by a high-frequency heating machine and infiltrates into the inside wall between the cap part 31 and the holder 4 and wets this wall, but this solder is repeled by the part of the resin coating 32. Since the neighborhood of the cap glass 33 is not heated by the solder 5, the cap glass 33 is kept free from the crack, etc., and the airtightness of the optical semiconductor element 3 is maintained.

IPC: H02K33/00
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To obtain a solenoid type oscillating actuator in which attraction of the armature can be enhanced, without increasing the magnetomotive force of a coil. SOLUTION: Two pole contact faces are constituted of the pole contact parts 5a, 6a which have hooked cross-section for attracting an armature 1.

Title: Color system discriminating circuit
Inventor: ANZAI SHUNICHI
IPC: H04N7/00
Filed: 1990-11-14
Abstract: PURPOSE:To offer the color system discriminating circuit giving stable operation without erroneous discrimination even under the weak electric field by discriminating whether or not the 'Lo' state of an ID signal is temporary and remaining unchanged when judging this phenomenon as temporary. CONSTITUTION:A synchronizing pulse generation circuit 55 generates a synchronizing pulse II to take the synchronization of rising by taking a clock CK of a period when an identification detection signal ID is 'Lo'. At this point, a mask pulse generation circuit 54 detects and judges whether or not the 'Lo' state of the identification signal ID is temporary, generating the mask pulse to mask the synchronizing pulse II when judged as temporary. Thus, the color discrimination signal ID synchronizing with the reference signal and not taking to 'Lo' when the identification detection signal ID becomes temporally 'Lo' can be obtained.

Abstract: PURPOSE:To eliminate the harmful effect on a living body and to obtain excellent compatibility, by coating the surface of Ti with Au, Pt or Pd extremely stable to the tissue of the living body and forming a mutual diffusion layer to the boundary part or the mutual diffusion layer with the third metal thereto. CONSTITUTION:Au, Pt and Pd are known as perfectly safe metals giving no harm to a living body but expensive alone and inferior to strength because of excessive softness. Therefore, this problem is solved by coating the surface of Ti with Au, Pt or Pd but Au, Pt or Pd merely applied to Ti is extremely easy to release. Therefore, the metal diffusion layer of Ti-Au, Pt or Pd is formed to the surface of Ti or the mutual diffusion layer of Ti-Au and the third metal X is formed and, thereafter, Au, Pt or Pd is further applied. It is necessary that the third metal gives no harm to the tissue of a living body and Si is pref. used as the third metal. Au, Pt or Pd and Si are applied to Ti in a thickness of 1-several mum by plating, vapor deposition or sputtering and heat-treated at 700-1200 deg.C under vacuum to form the diffusion layer.

Filed: 1988-12-08
Abstract: PURPOSE:To constitute a system capable of accommodating many subscribers with high frequency utilizing rate and high service performance by providing the center judgement of such events as location registration of a portable telephone set and at the time of outgoing and incoming calls. CONSTITUTION:A portable telephone set(PTEL) has a function applying-access to a ratio system controller RCE via a fixed radio station (FRS), applying automatic position registration, and accessing the radio system controller RCE to vary the location registration when the necessity of location registration to other fixed radio station takes place.
